It is a quill pen and also a white bird feather.

The SBSAR allows the colours of the feather to be changed. The curvature can also be adjusted.

It is important to apply subsurface scattering in the shader. Otherwise, the feather will look like a hard material rather than soft and fluffy texture.

They are brown rocks covered by fresh snow. Some snow has melted leaving damp mark on the snowy ground.

With the sbsar file, rock size, snow level and fresh and melted snow amount can be controlled.

This is a texture generator of sunny side up egg. With the sbsar file, tons of PBR texture variations of sunny side up eggs can be generated. The adjustment includes broken egg white, white white bubbles, burnt edges, holes and so on.

It is a foam board or technically, polystyrene material. The pattern of monomer can be found on the surface of this synthetic aromatic hydrocarbon polymer.

It is a ice texture. It can also be treated as frozen substances in the nature. On the ice, there are a lot of cracks. Though it is an icy texture, it mixes with some snow.

It is a snowy ground which is melting. Frozen ice can be found in between snow. By close examination, icy cracks can be observed.

With the sbsar file, the balance between snow and ice can be adjusted.

It is a simply rock texture, but can be applied to a large varieties of natural environment. It is simple, but useful.

It can be used to texture a single stone or as a rocky ground of cliff.

It is a spider web. Some people may call it cobweb. Technically they are different, but most people use these 2 terms interchangeably.

With the sbsar file, you can control the damage level and number of silk lines. Besides, the deformation can also be controlled.

It is a concrete wall with some plaster, but has numerous dents of various sizes due to bumps, hits or shots.

This texture is an imperfection. It is glass stain. When a glass of cold drink is put on a cloth, it will leave a water stain.

There are 6 variations which should be enough for scattering randomness.

It is a tree bark texture. From its horizontal patterns and the peeling, we can tell it is a birch tree.

It is a a plaster wall painted in white, but leaving prominent paint marks due to poor workmanship.

Pores can also be found on this concrete plaster texture.

Its normal map can be used as an imperfection or decal for walls.

It is a fingerprint texture which can be used to create imperfection on smooth surfaces, especially reflective materials.

It is a plain fabric cloth, but it is very useful to texture cushions, pillows, bed sheets etc.

By close examination, the micro-texture of the cloth can be seen.

Its normal map can be applied to any graphical patterns(plain image) you want. Then it will create a realistic fabric object such as sofa.

It is a concrete texture composed of Corinthian columns. Due to weathering and aging, a lot of wear and cracks appear on the surface.

Despite its name columns, this texture suits extremely well for walls and urns.

It is a concrete wall made of numerous concrete plates. Due to weathering, the concrete plates have cracks, pores and dirt.

If you are going to 3D model a concrete wall, please do not miss this texture!

It is a classical corrugated metal sheet where is commonly used to build walls of factories or construction sites.

Dirt and edge wear can be found on this texture.

It is a black floor with commonly seen white dot pattern. Dirt can easily be found on the surface, so it is a perfect texture for paving a ground of public area in your CG scene.

This is a stucco plaster. By examining the surface, a lot of fan shape trowel strokes or marks can be found.

This is a typical rocks that can be found near seashores. It is largely covered by barnacles and mosses.

Some barnacles are alive while some have became empty shells leaving a hole.

To texture a rocky seashore? This texture is absolutely a good choice.

To achieve a better result, I'd recommend to use it with the height map as well.
